MODULE 5 EXERCISE PROBLEM
Calculate the size (in horsepower, HP) of a pump required to move water moving at three
different average velocities of 5, 10, and 15 feet per second through a 5,000-foot long pipe with a
1-inch inside diameter. Assume that the viscosity of water is 0.01 poise at room temperature and
that the pump has an efficiency of 0.70. Create one Mathcad worksheet file for each of the
velocities to be tested. Show all your complete solutions.
